Loss of power.

[jaschlum]

I have a 92 XLT. It is slipping while idling (not to bad) and recently i feel the exhaust has smelled worse and the fuel economy has gone down and a loss of power. I replaced all the spark plugs and wires and it seemed to help a little. Along with putting some fuel injector and filter cleaner into the tank. Is there anything else i can do to gain back some power and fuel economy? Thanks for the help!

Welcome to this forum! I've moved your thread into the stock 91-94 section. Do you have any codes? The PCM should have a trouble code stored if you see a check engine light.

O2 sensor? Maybe check the fuel filter. I changed mine last summer, turns out it was the original, and it helped quite a bit.

Check all of the above but also check the fuel pressure regulator. Pull the vacuum line to the FPR and see if there is gas in the vacuum hose. A bad or leaking FPR will cause poor fuel economy, poor idling and running and poor performance in general as well as a strong unburnt fuel odor in the exhaust.
